Re: LZ4 decoder (assembler)

Great stuff Anima and Leonard!

Apart from the 4k binary Cyprian tried, has anyone done any other tests regarding pack ratio? I'm still favouring ARJ mode 4 and 7 for max pack ratio, but this looks like a great alternative for when depack speed is crucial.

@ggn, is there a tuto to know how DSPmod34 works and how use it for sample playing (maybe a simple source code playing a .mod while playing 2 or 3 samples) ? It's my first try on Atari Falcon :) Thanks again my Friend ;) Sure thing! You can start without even integrating it in your code to see how ...

Re: WIP - StepFive - Amiga Musics + SFX on falcon...

Check out DSPmod34 (http://dhs.nu/files.php?t=democreation), it supports up to 4 channels music + 4 channels of sound effects.

Good luck with your game!

Re: Atari Legend is back! Updates thread...

After checking Ultima V, it does show the credits if you setup Steem to 1 Mb. The game itself runs just fine even with 4 Mb. Also the credits part runs just fine on real hardware and as it seems you are eager to know who made the game, here you go :) (taken from a 14Mb Falcon): FWIW here's the prob...

Re: efficient polygon drawing

How is the XOR filler done? Sounds interessting to try it out with the blitter? But I can't see how it can automatically draw a line? It seems like all that will happen is that black pixels turn white (0 to 1) and the opposite. Nothing else. Take a look at this siggraph paper co-written by Rob Pike...

Beyond Brown - "new" website for Atari tech and stuff!

It started as nothing too serious, just a place where we can dump info and blog-type posts that are too big and cumbersome for forums.

Re: Falcon: Painters or converters that save in raw format

Photochrome should manage Falcon formats. I'm not sure if Doug added it to some internal betas, so if the latest release doesn't have it we should prod Doug to release a newer version :)

It seems like a good solution to fit a cosmosex internally (if it works!) and solves the cabling problem.

Re: gcc 7.1 for the ST series

Well, -Ttext=0 is there. Another thing is that I have to manually specify -fleading-underscore, otherwise my code doesn't build, but it's already there in CFLAGS_FOR_TARGET.

Re: gcc 7.1 for the ST series

Did you link with "-Ttext=0"? If not, try enabling that as I suspect that's the issue. That did the trick. So, why does it default to putting .text at an 0x80000000 offset? Is it just an Linux and/or ELF thing? Pretty much yes - I think this is a default value mandated by the ELF format, ...
